RICE-BEATER.

SPECIFICAFION forming part of Letters Patent No. 271,810, datcgd February 6, V11.883,

Application tilcdApril, 1882. (Nomodel.)

To all whom it may concern: A

Be it known thatl, JAMES DECKER, of Surrency, in thecounty of Appling and btate of Georgia, have invented a new and useful Im- 5 provement in Rice-Beaters, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the tigures.

Figure 1 is a l'ront elevation of my improvement, partly in section. Fig..2 is a sectional .elevation ofthe same, taken through the broken line a: w, Fig. 1. Fig. 3 is a. perspective View of the pestle, showing a modified forni.

The object ot' this invention is to facilitate the beating of rice, to remove the inner skin, and clean and polish the kernels after the rice has been hu-llcd.

The invention consists in the peculiar coustruction and combination of the parts, as'will be hereinafter fullyT described andclaimed.

A is a vertical frame, which is attached to a base, B, ot' such a length and breadth as will give a stable support to the machine.

, To the upper part of a central bar, A, of the frame A is journaled a crank-shaft, (l, to

. the middle part of which. is attached a pulley,

D, to receive a driving-belt.

E, attached to the said shaft, are pivoted the upper ends of pitmen F, the lower ends of which are pivoted to the bars G, that slide u pand down along the central bar, A', ofthe frame A, and

are slotted vertically to receive the guide-pins H attached to the said cent-ral bar, A', to cause the said bars G to move up and down vertically. The slide-bars G pass through guideholes in thecentral cross-bars, A, ofthe frame A, and to the opposite sides of their lower ends 'are bolted boards I, whichare tapered toward their lower' ends, and serve as pestles to beat the rice. By placing blocks against the outer sides of the upper ends of the boards I, and otherboardsagainstthe said blocks,andlength ening the bolts J, that secure the boards I to the bars G, so as to pass` through the added l blocks and boards, the pestles can be enlarged to any desired extent. if desired, a cross-bar,

K, can be attached to th'e lower end of each l bar G, and downwardly-projectingtapered bars To thecranks ofthe shaft(),`or to crank-Wheels' to operate upon the rice more quickly. The

cranks of the crank-shaft O project. in opposite directions, so that the pestles I will always move in opposite directions to balance the machine and allow the rice to have a free movement when operated upon by a pestle.

' M isthe mortar, which is made in the form of a cylindrical tub, and is pivoted at the center of its bottom toa pivot, N, attached to the lowest cross-bar, A3, of the frame A.

To the bottom of the mortar M is attached, or upon it is formed, a worm-wheel, 0, the teeth ot' which mesh intothe threads ot'a worm, P, attached to theshaftQ. The Worm-wheeland wormcan be replaced by beveled-gear Wheels, if desired. The shaft Q revolves in bearings attached to the lower part of the frame A, and to it is attached a pulley, R, around which passes an endless band, S. The band S also passes around a pulley, T, attached to the crank-shaft C, as shown in Fig. 1.

'the mortar M rotated by the revolution of the crank-shaft O, and the pestles will thus be brought in contact with all thc rice in the mortar. With this construction the inner skin of the rice-kernels will be quickly beaten and rubbed ott', cleaning and polishing the said kernels, and any kernels ot' green rice contained in the mortar will bc ground to powder. Aftertherice has been sufficiently beaten, the dust is blown oft' by fans in a fanningmill or other suitable machine. Y

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A rice-beater constructed substantially as herein shown and described, consisting of the frame A B, the crank-shaft G, the pitmen'i F, the sliding bars G, the pestles I, the rotary mortar M, and its driving-gearing, as set forth.

2. In a rice-beater, the combination, with the sliding bars G, carrying the pestles I, of the crank-shaft U, the pitmen F, and the guidepins H, substantially asl herein shown and described, whereby the pestles will be operated in vertical lines by the revolution of the crankshaft, as set forth.

3. vIn a rice-beater, the pestles consisting ot' By this construction the pestles I will be operated and IOO two or more tapered boards, I I, in comhinaand d scribed, whereby the mortar will be r0- tion with the lower ends of the slide-boards G, tated bythe shaft; that operates the pestles, as

substantially as herein shown and described. set forth. y
